"None of [the jewelry] was custom made - all of Keira's jewelry comes from Chanel. It's all real, so in every scene she wears real diamonds [or pearls]. And it's not vintage; every piece is from Chanel's fine jewelry collection. But we used things that we thought matched the mood of Anna Karenina. And because we were stylizing the look and we weren't being accurate about [being in] 1879, it didn't bother me at all to use modern jewelry."
